Well, we aren't. We are applying cost benefit analysis, which is subjective. Society agrees pretty uniformly that motor vehicles are worth the risk. It's the same with guns, there just isn't as much of a consensus. Some people thing the risk is worth it, others don't.
If you frame it as a binary right and wrong based on your own risk tolerance rather than making genuine arguments for certain trade offs you aren't having a good faith conversation, which is what I was satirizing.
